BUMPER roe AUTOMOBILES.

Application filed June 6, 1921. Serial No. 475,371.

T 0 all whom it may concern;

1 Be it known that we, J AMES TURNER and PEARL P. CRABYLL, citizens ofthe United States, residing at Springfield, in the county ot' Cl ark andState of Ohio, have invented certain new and useful Improvements inBumpers for Automobiles, of which the following is a specification. I

This invention relates to improvements in bumpers for automobiles, itrelating more PitlftlC'tllLIly to that type of bumper in which thebumper bar and the supporting arms for same are constructed of springsteel with the arms integrally formed with the bar.

One of the objects of: this invention is to provide for more effectivelysupporting and racing the bar from the vehiclcframe, and

for eliminating vibration in the bar itself. A further object of theinvention is'to provide a reinforce for the bar of a resilient naturewhich will aid the bar in resisting shocks.

In the accompanying drawings Fig. 1 is a top plan view'of a bumperembodying the improvements.

2 is a front elevation of the same.

Fig. 3 is an enlarged top plan-wiew of: portion of the same.

Fig. 4- is also a top plan view showin modification in the manner ofattaching bumper to the vehicle.

Referring to the drawings. 1. represents a bumper bar formed of fiatspring steel, the ends of which are bent back in substantialparallelism' with the bar proper. as indt cated at 2. and thencerearwardly as indicated at 3 to provide attaching arms. Connected to thebar 1 at points suitably re moved from the center thereof by clips arebraces 5, also constructed of flat spring steel similar to the materialof the bar. Each of these braces is bent on a broad curve with the rearend thereof extending parallel with its companion arm 3, and the forwardend. lying parallel with the bar 1.

In the construction shown in Figs. 1 to,

8, the arm 3 and brace 5 are connected by bolts 5 with the shank 7 of avertically arranged head 8, the rear side of which is channelled, asindicated at 8 to fit the lamp bracket 6 of the vehicle being clampedthereto by the clip 9; this particular form of connection being oneparticularly intended for the Franklin car.

Nhen the bumper is to be applied to other cars having channelled frames,other means of securing it in position may be employed, one of. which isillustrated in Fig. i. in this figure, 10 represents the forward portionof one of the channelled side members ofthe vehicle partly broken awayto show a clamping member 11 arranged to be clamped to the lower flangeof the frame by a wedge 12, the wedge portion of which is arrangedbetween the lower side of the frame flange and an inclined face onthe clamp li. a' bolt 13 .ieing employed to draw the parts together. The arm 3and rear portion of the brace 5 are preferably connected by rivet letand are received in a channelled plate 15 arranged between the nut ofthe bolt and the wedge 12. This form of con nection more fully describedin our pends ingapplication Ser. No. eeiQQ-iQ filed February 3, 1921.

In order to reinforce the bumper ba proper 1 there is secured to the forart preferably of spring steel, repre ente'd 3 16 and 1?. The'endsofthese strips are arranged in planes parallel ith the bar 1 so as to beclamped thereto by the clips but a side thereof by the clips at a pairof strips.

the intermediate portion of the ouer st p 17 is bowed on the'arc of acircle inner strip 16 has its central portion :th the apex thereofcontact to providr a reintruss; the

in a i-form it with the strip 17 so force therefor in the to;

bent portion of the strip to being of lesser length than that the one '1T By the construction described. it will be seen that the bumper barprope l is not only firmly secured to and braced iii-om the we hicleframe, but also has a substantial reinforce in its forward side, thesedo ices aid ing the bar in a material manner in resisting the shock ofcollision and materially reducing the danger of breakage to the bumperitself.

While we have shown the braces 5 connected to the bar 1 by the clips l,yet an equally good form of connection can be had by rivetting the outerends of the braces to the bar.

Having thus described our invention, we claim 1. In a bumper forautomobiles, a bar, together with. means for attaching the same to thevehicle and a pair of fiat resilient strips having their respective endsarranged I parallel to said bar and to each other toto said bar, theouter strip being bent forwardly from said bar and a' lesser length ofthe inner strip being also bent forwardly from said harm contact withthe inner side of said forward strip.

2. In a bumper forautomobilega bumper bar, together with means forconnecting the same to the vehicle, and a pa1r of reinforc-r ing stripsconnected to the forward side of body lportion of the other strip. O U-n a bumper for automobiles, a bar formed of flat resilient materialhaving its rearend bent to form supporti.ngarins to attach the same tothe vehicle, a pair of fiatresilient strips having their respective endsarranged parallel to said bar and to each other together with means forcon necting the same to said bar, the outer strip being bent forwardlyfrom said bar and a lesser length of the inner strip being also bentforwardly from said bar in contact with the inner side of said forwardstrip.

4. In a bumper for automobiles, a bar having its ends bent to formresilient attach ing arms, resilient braces for said bar, each bracebeing bent so that its forward end will lie parallel with the bar andits rear end parallel with its companion arm, means for connecting thebraces to the bar and also for connecting the braces and ar'ms'to thevehicle, two reinforcing strips. on the away from said mainbar andarranged to yield toward the same under shock at; all

points between its connected ends,

6. In a bumper for automobiles, a' bar formed of resilient material,integrally formed supporting arms projectingffroin the ends of said barin a general rearward direction, a pair of braces of resilient material,each of said braces having its forward end arranged parallel to andconnected with the rear side ,of said bar and its rear end arrangedparallel to and connect-ed with its companion supporting arm, and areinforcing strip for the forward-side'- of said bar, said reinforcingstripbeing bowed away from said bar with its ends secured thereto andoverlapping said braces. j

In testimony whereof we have hereunto set our hands this 23rd day of 1921.
